These are the 12 Steps you need to do to create your own real hologram on glass with DCG (dichromated gelatin):
0:00 Introduction
0:13 Step 1 – Checking the glass – To get the perfect Hologram you have to check the orientation of the “parallel-lines-pattern” inside the glass.
1:53 Step 2 – Cutting the glass – With a good cutting technique you will waste less glass in your hologram production.
4:12 Step 3 – Cleaning the glass – An Overview of the best chemicals for glass cleaning and how to detect the correct side for coating the glass.
6:26 Step 4 – Preparing the gelatin – Some proven DCG Hologram recipes and how they are adjusted for different temperatures and laser wavelengths.
9:49 Step 5 – Sensitizing the gelatin – How to add the Ammonium Dichromate to the gelatin mix and properly filter it.
13:08 Step 6 – Coating the glass – Working in a controlled coating environment makes better, cleaner holograms and also keeps you safe.
16:07 Step 7 – Building the exposure setup – Instructions on how to build a holographic recording setup.
18:03 Step 8 – Exposure – Expose your coated plates correctly to get the best holograms.
22:37 Step 9 – Developing – Keeping the many variables under control makes this the most crucial and difficult step in the hologram production.
30:38 Step 10 – Scraping – By removing some of the gelatin the Hologram will be properly framed.
33:49 Step 11 – Sealing – Using Epoxy Resin and gluing a cover plate on the hologram will protect it from moisture and preserve it for many years.
39:44 Step 12 – Grinding – Taking off the sharp edges from the glass will make the Hologram safer and more presentable.

This is one of those "If it was easy, everyone would be doing it". It must have taken a huge amount of time to work out the details of this procedure. Even with your exact instruction, replicating the process is not trivial. This video documenting your procedure is excellent, you have my respect.

This is the first time I've downloaded a youtube video just to back it up in case the internet is shut down or something... just amazing!
-
this is by far the best technical insight I've ever seen on youtube. keep up the good work!
-
Finally a video that walks thru the process in good detail. I’ve been looking for video tutorials on holography for years. Thanks for the effort and sharing your knowledge and experience.
-
Thank you for making such a clearly defined procedural map. Excellent work.
-
This is really incredible. What an awesome resource this single video is. Fantastic work, though that doesn’t do justice to the work you’ve clearly put in here. Thank you.

I learned about holograms in books as a young child (where I learned you need to minimise vibration in your studio!) and saw my first ones in a museum wayy back in the 80s. I've learned about them in science class. I'm no genius but I do have a fair grasp on some physics including some quantum mechanics and rudimentary signal theory, but for the life of me, no matter how hard I've tried over the last 30-odd years, I cannot understand how a hologram manages to manipulate the light to reproduce that 3D effect, and it's clear that no teacher I've asked actually understood it, either. Sure, read up on it, it's "interference patterns" yada yada.. but it still doesn't make sense. It's just mindblowing. Your example hologram at the end is amazing. The 3D structure actually obstructs itself as you turn it around. Incredible.

Wow. That's dedication. This is what humans should be striving for. The passion you exhibit is admirable. Well done.
-
I was a kid in the 90’s. I appreciate this artwork so much. I never knew the process until now. Thank you for teaching us.
-
thank you, made my first holo's, in 76' 77 ( still have them ) with Fred Unterseher in berkley,ca. met Richard Rallison and saw his first dicromates. WOW rich said he burned down his dads barn learning to make DCG's . most people have never seen a real holo on glass and fewer have seen DCG bought some DCG's from holo's gallery on haight street in san francisco early 90's they are beautiful your vid is a master work....Gary

While watching the video, I interrupted several times to google the components and the experiment room.) Thanks for sharing the technology. Everything is very detailed and all conditions are taken into account.

This is the best video on YouTube
-
Danke Sven, tolles Video und geniale Anleitung. Man merkt mit jedem Wort wie passioniert du mit/bei deinem Projekt bist, großartig!
-
Seems like you just need bigger fluid holding tubs and glove boxes, and tools, just bigger everything to achieve your dream. I would love to see this hologram in the desert. Thank you for all your dedication and passion and hard hard work in getting this info to us. I am starting a company soon and my ultimate goal right now is to get a hologram on something you've probably never seen a hologram on before. I know it's not going to be easy and I'll probably fail 1000 times before it works. I might have some questions in the future, you will be my main guy to ask if I hit some road blocks. I hope to hear from you in the future. Thanks!

Swann, this is a masterwork! When I last did holographry in college, we had a Newport table on top of wool and inner tubes, a magnetic long bore gas laser, spatial filters, polarizers, beam splitters and balancers, dark rooms, stopwatches, and pricey Kodak film. I love your exposure setup, you make it look easy.

Thanks for putting this video together, so valuable. I'm not sure if I will ever make a hologram but if I do I know where to look. Very impressive. And good luck with the 2 meter hologram!
-
You deserve a medal 🏅
-
Thank you for such a perfectly articulated instruction..details that are mandatory were not neglected and i am so grateful that ypu would take the time to deliver this information with such detail and perfection..i think you gather how thankfull i am for what you've gifted here..you rock this concept!
-
One of the best videos I've seen on YouTube. Especially love all of the DIY laboratory equipment.
-
Gotta love the German attention to detail! 🙃
